FIELD: construction.
SUBSTANCE: method of manufacturing a tamper-proofing machine includes the provision of forging with reinforcing elements made in the form of combined parts. Each part is made of a material that has a weldability with the material of the forging, a substrate. In the body of the substrate, the carbide element is rigidly fixed. The forging is performed by welding its upper and lower parts. The upper part of the forehearth is a heel pin or a punch rod, the lower end of which has a broadening in the form of the upper part of the blade adjacent to the stem. The lower part of the heel is, respectively, the blade or the lower part of the blade. The lower part of the forehearth is made of a combined part which is fixed so that the axis of the part is parallel or constitutes an acute angle with the longitudinal axis of the forehearth.
EFFECT: increasing the life of the heel.
